IMPROVEMENT IN JOINTS FOR PAPER BARRELS.

Specification forming part of Letters Patent No. 175,138, dated March21, 1876 application filed January 8, 1876.

To all whom it may concern p Be it known that I, WILLIAM H. MURPHY, ofSyracuse, in the county of Onondaga and State of New York, haveinventeda new and useful Improved Joint for Paper Packages,

which I have fully described in the following specification, referencebeing bad to the accompanying drawings, in which- Figure 1 represents aperspective view of the same on the front side; Fig. 2 a perspectiveview of the same on the inner side, and Fig. 3a transverse sectionalview.

In Figs. 1 and 2 a portion of the completed joint is represented asbroken out, in order to better show the manner in which the parts areput together.

The object of my invention is to make a strong joint in paper packagesmade with one or more joints, and, at the same time, dispense entirelywith any form of dovetailing.

In making this joint, I first take the piece of wood A, or it may be ofmetal, made in the form or shape shown in the drawings, and a littleshorter than the length of the proposed joint, and having two sideprojections or lips, a a, and a central raised portion, b, raised abovethe plane otthe lips a a just about the thickness of the paper used inthe package.

I then take a strip of metal, B, iron, tin, or

zinc, of about the same width as the piece A, and a little longer thanthe proposed joint. I

then place the edges of the paper 0, which I simply cut straight, uponthe lips 11 a of the piece A, with their edges against the projection b.I then place the strip B over the whole, and, nailing through this andthe edges of the paper 0 into the piece A, on both sides of the centralraised portion b and through the strip B into the part b of the piece A,I make a tight and a very strong and durable as well as simple joint;or, in a package made with abilge, I can make my joint by nailing thestrip B to the raised portion of the piece A, and inserting the edges ofthe paper in the spaces thus formed therefor, when, by simply drivingthe hoops down, the paper is forced closely into the spaces and thus thejoint is made tight and the strength and durability are, if anything,greater than when. made in the other way.

After thus forming the joint the ends of the strip B may be cut 01?flush with the ends of the package, or may be bent tightly over the endsof the package and down a little way on the inside.

I make the piece A a little shorter than the proposed joint in orderthat, when the joint is formed, the upper and lower ends will be out ofthe way for the insertion of the heads; and it may be made of suchlength as to make a slight shoulder for the head to rest upon and toprevent its being forced too far into the package. I thus make a verysimple and, at the same time, excellent joint for paper packages.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the piece A, having the lips a a and the raisedportion b, the strip B, and the paper 0, made and operated substantiallyas above described.
